Does anyone have any pictures of a Rupp mini go with the correct engine and gas tank. I read in the book that it should have a Tecumseh 3.5 hp engine, however I have read somewhere that the early ones came with a Clinton engine. This would make some sense as I have a Rupp Herbie go kart that did indeed come with a Clinton engine. Also mine has a plate stamped into the frame with a serial number, does anyone know how to decipher it? Thank you
